Consume items on the map

The functions here consume accessible items / item charges on the map or in vehicles around the player (whose positions is given as origin).

They return a list of copies of the consumed items (with the actually consumed charges in it). The quantity / amount parameter will be reduced by the number of items/charges removed. If all required items could be removed from the map, the quantity/amount will be 0, otherwise it will contain a positive value and the remaining items must be gathered from somewhere else.

Detailed Description

Manage and cache data about a part of the map.

Despite the name, this class isn't actually responsible for managing the map as a whole. For that function, see mapbuffer. Instead, this class loads a part of the mapbuffer into a cache, and adds certain temporary information such as lighting calculations to it.

To understand the following descriptions better, you should also read Map Management

The map coordinates always start at (0, 0) for the top-left and end at (map_width-1, map_height-1) for the bottom-right.

The actual map data is stored in submap instances. These instances are managed by mapbuffer. References to the currently active submaps are stored in map::grid: 0 1 2 3 4 5 6 7 8 In this example, the top-right submap would be at grid[2].

When the player moves between submaps, the whole map is shifted, so that if the player moves one submap to the right, (0, 0) now points to a tile one submap to the right from before

Takes a vehicle already created with new and attempts to place it on the map, checking for collisions.

If the vehicle can't be placed, returns NULL, otherwise returns a pointer to the placed vehicle, which may not necessarily be the one passed in (if wreckage is created by fusing cars).

Parameters
vehThe vehicle to place on the map.
merge_wrecksWhether crashed vehicles become part of each other
Returns
The vehicle that was finally placed.

Apply trap effects to the creature, similar to creature_in_field.

Parameters
critterCreature that just got trapped
may_avoidIf true, the creature tries to avoid the trap (Creature::avoid_trap). If false, the trap is always triggered.

◆ draw()

void map::draw ( const catacurses::window w,
const tripoint center 
)

Draw a visible part of the map into w.

This method uses g->u.posx()/posy() for visibility calculations, so it can not be used for anything but the player's viewport. Likewise, only g->m and maps with equivalent coordinates can be used, as other maps would have coordinate systems incompatible with g->u.posx()

Parameters
wWindow we are drawing in
centerThe coordinate of the center of the viewport, this can be different from the player coordinate.

template<typename Functor >
void map::function_over ( const tripoint start,

Runs a functor over given submaps over submaps in the area, getting next submap only when the current one "runs out" rather than every time.

gp in the functor is Grid (like get_submap_at_grid) coordinate of the submap, Will silently clip the area to map bounds.

Parameters
startStarting point for function
endEnd point for function
funFunction to run

Place items from item group in the rectangle f - t.

Several items may be spawned on different places. Several items may spawn at once (at one place) when the item group says so (uses item_group::items_from which may return several items at once).

Parameters
locCurrent location of items to be placed
chanceChance for more items. A chance of 100 creates 1 item all the time, otherwise it's the chance that more items will be created (place items until the random roll with that chance fails). The chance is used for the first item as well, so it may not spawn an item at all. Values <= 0 or > 100 are invalid.
p1One corner of rectangle in which to spawn items
p2Second corner of rectangle in which to spawn items
ongrassIf false the items won't spawn on flat terrain (grass, floor, ...).
turnThe birthday that the created items shall have.
magazinepercentage chance item will contain the default magazine
ammopercentage chance item will be filled with default ammo
Returns

◆ save()

void map::save ( )

Add currently loaded submaps (in grid) to the mapbuffer.

They will than be stored by that class and can be loaded from that class. This can be called several times, the mapbuffer takes care of adding the same submap several times. It should only be called after the map has been loaded. Submaps that have been loaded from the mapbuffer (and not generated) are already stored in the mapbuffer. TODO: determine if this is really needed? Submaps are already in the mapbuffer if they have been loaded from disc and the are added by map::generate, too. So when do they not appear in the mapbuffer?

◆ abs_sub

tripoint map::abs_sub
protected

Absolute coordinates of first submap (get_submap_at(0,0)) This is in submap coordinates (see overmapbuffer for explanation).

It is set upon:

  • loading submap at grid[0],
  • generating submaps (generate)
  • shifting the map with shift
